CPP Extension - CMake Error - SuiteSparse::umfpack not found

5 months 3 weeks ago #2515 by creativeworker
Hello,

i just updated my NGSolve to the newest version. Unfortunately, now I cannot compile my CppExtension module. The CMake Error is:
CMake Error at C:/Program Files/ngsolve-v6.2.2002/cmake/NGSolveConfig.cmake:79 (add_library):
  Target "ngsextension" links to target "SuiteSparse::umfpack" but the target
  was not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?

Did I mess up something? Or was there a change regarding that?

Thanks in advance for your help!

Unfortunately, I still couldn't find a fix for the issue. I'm using NGsolve 6.2.2003...

Hej!
I ran into the same error using NGSolve 6.2.2004 when trying to build the current version of mylittlengsolve following the tutorial:
ngsolve.org/docu/latest/mylittlengs/1_Basic/README.html

This should probably be addressed by the developers.

Using v6.2.1907 worked just fine.

Which version of CMake are you both running? Try to upgrade to the latest one. Note: cmake.org seems to be down currently, the installers are also available on github: github.com/Kitware/CMake/releases

I used CMake 3.16.x and updated today to CMake 3.17.2 but without success.
